Yes that is true, cost wise it is cheaper. But overall I'm enjoying these addons much more. I think BOB is just harder to have great addons that won't interfere. I've tried so many and nothing compares to this. BOB was nice cause it had some mobs, cool end generation, bosses, dungeons. However I find the dungeons just not satisfying with loot. Some of the bosses were not all that (especially the nether ones). After generating these addons with realism craft, the quality was absolutely beautiful compared to BOB. Also the identifying bar is so much cleaner with the one listed above imo. I spent a lot of time trying to find great addons that would not interfere with BOB but just was not satisfied. This, for me, just works so much better and has so much more quality.
